What happens if you miss the Tax Return deadline?

Failing to lodge your Tax Return by the cut off date, 31st of October, will incur late lodgement penalties. Possible penalties include:

  • 28 days past the tax deadline – $222
  • Every subsequent 28 days after the first period will see this penalty double up all the way up to $1,110.

Can you get a tax deadline extension?

The good news is, that if you have an appointed tax agent with One Click Life, you can opt in for a tax deadline extension. This means you can lodge your Tax Return after the cut off date 31st of October, and have until the 15th of May the following year. It’s important to note, the ATO may refuse your extension if you have any outstanding previous years’ Tax Returns, or a history of late returns. 

Remember, tax deadline extensions are only available if you have already appointed a tax agent prior to October 31st. Speak to our qualified tax accountants today about a tax deadline extension, or click here to get started now on your Tax Return.
